Name:_______________________________ EE 4002-2 Test # 2 SSN: _______________________ Spring 2004 This test is open book, and notes: 1. For the circuit below, determine the filter order, filter shape (HPF, LPF, BPF, or BSF), and the filter type. 2. A 3 dB attenuator is placed on a network analyzer to verify that the loss is in fact 3 dB. The following S-parameters are observed. What is the actual attenuation of the device?

Design a biasing network for a 1 GHz BJT inverter with a bypassed R E . 6. Design a T-type matching network that transforms a Z L = 100 load to Z IN = (20-j40) . We wish to create a nodal quality factor of Q n = 4 with this matching network. The matching should be achieved at 600 MHz. The characteristic line impedance is 50 . 7. Find the ABCD-parameters for the following three-element pi-network....
